begins on such day (and if such day is not a Business Day, the immediately preceding Business Day) plus 1%. Any change in the Alternate Base Rate due to a change in the Prime Rate, the Federal Funds Effective Rate or the LIBO Rate shall be effective
from and including the effective date of such change in the Prime Rate or the Federal Funds Effective Rate, respectively. 







 “Applicable Percentage” means, with respect to any Term Lender, the percentage
identified as its Applicable Percentage opposite such Term Lender’s name on Schedule 2.01 hereto, as such percentage may be modified by assignment in accordance with Section 9.05 hereof. 

“Applicable Rate” means with respect to (a) the Loans made to the Borrower, the applicable rate per annum set forth
below under the caption “Eurodollar Spread” for Loans comprising Eurodollar Borrowings or “ABR Spread” for Loans comprising ABR Borrowings, as the case may be, based upon the ratings by Moody’s and S&P, respectively,
applicable on such date to the Index Debt for the Borrower or (b) with respect to the commitment fees payable hereunder, the rate per annum set forth below under the caption “Commitment Rate” based upon the ratings by Moody’s and

Spread	 	 	ABR Spread	 	 	Commitment

ratings; and (iii) if the ratings established or deemed to have been established by Moody’s and S&P for the Index Debt shall be changed (other than as a result of a change in the rating system of Moody’s or S&P), such change
shall be effective as of the date on which it is first announced by the applicable rating agency. Each change in the Applicable Rate shall apply during the period commencing on the effective date of such change and ending on the date immediately
preceding the effective date of the next such change. If neither Moody’s nor S&P shall have in effect a rating for the Index Debt, then the ratings for the Index Debt shall be deemed to fall within Category 5. If the rating system of
Moody’s or S&P shall change, or if any such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to amend this definition to reflect such changed
rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Rate shall be determined by reference to the rating most recently in effect prior to such change or
cessation.

or Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise

Section 2.07 Funding of Borrowings. 

(a) Each Term Lender shall make the Loan to be made by it hereunder on the applicable Advance Date by wire transfer of immediately available
funds by 1:00 p.m., New York City time, to the account of the Administrative Agent designated by it for such purpose by notice to the Term Lenders. The Administrative Agent will make the Loans available to the Borrower by promptly crediting the

 (b) Unless the Administrative
Agent shall have received notice from a Term Lender prior to the proposed date of any Borrowing that such Term Lender will not make available to the Administrative Agent such Term Lender’s Pro Rata Share of such Borrowing, the Administrative
Agent may assume that such Term Lender has made such Pro Rata Share available on such date in accordance with this Section 2.07 and may, but shall not be required to, in reliance upon such assumption, make available to the Borrower a
corresponding amount. In such event, if a Term Lender has not in fact made its Pro Rata Share of the Borrowing available to the Administrative Agent, then the applicable Term Lender and the Borrower severally agree to pay to the Administrative Agent
forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of

Borrower the amount of such interest paid by the Borrower for such period. If such Term Lender pays its Pro Rata Share of the applicable Borrowing to the Administrative Agent, then the amount so paid shall constitute such Term Lender’s Loan
included in such Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Term Lender that shall have failed to make such payment to the Administrative Agent.

this Section. The Borrower may elect different options with respect to different portions of the Loans, in which case each such portion shall be allocated ratably among the Term Lenders holding the Loans comprising such Borrowing, and the Loans
comprising each such portion shall be considered a separate Borrowing.

election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery, fax or emailed pdf to the Administrative Agent of a written Interest Election Request signed by the Borrower. 

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.03:

and of such Term Lender’s portion of each resulting Borrowing. 
 (e) If the Borrower fails to deliver a timely Interest Election
Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR
Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is
continuing (i) no outstanding Borrowing of the Borrower may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Borrowing of the Borrower shall be converted to an ABR Borrowing at the end of the Interest
Period applicable thereto. 
 Section 2.09 Reduction and Termination of Commitments. 

  
 28 








 (a) On each Advance Date, each Term Lender’s Commitment shall be automatically and
permanently reduced by the amount equal to the Loan made by such Term Lender on such Advance Date. 
 (b) The unused Commitments shall
terminate in their entirety on the last day of the Availability Period (after giving effect to the incurrence by the Borrower of the Loans, if any, on such date). 

(c) Notwithstanding the foregoing, all of the provisions of the Loan Documents which by their terms survive termination of the Commitments,
including, without limitation, those provisions set forth in Section 9.06, shall survive and not be deemed terminated, but shall remain in full force and effect. 

Section 2.10 Repayment of Loans; Evidence of Debt. 

(a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the ratable account of each Term Lender the then
unpaid principal amount of the Loans (and all accrued and unpaid interest thereon) made to the Borrower on the Maturity Date. 
 (b) Each
Term Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Term Lender resulting from the Loan made by such Term Lender, including the amounts of principal and interest
payable and paid to such Term Lender from time to time hereunder. 
 (c) The Administrative Agent shall maintain accounts in which it shall
record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Term Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Term Lenders and each Term Lender’s share thereof. 

(d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie
evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Term Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation
of the Borrower to repay the Loans made to the Borrower in accordance with the terms of this Agreement. 
 (e) Any Term Lender may request
that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Term Lender a promissory note payable to the order of such Term Lender and substantially in the form of note attached
hereto as Exhibit E. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.05) be represented by one or more promissory notes in such form
payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). 

Section 2.11 Prepayment of Loans. 

  
 29 








 (a) Optional Prepayments. The Borrower shall have the right at any time and from time to
time to prepay any Borrowing, in whole or in part, subject to prior notice in accordance with paragraph (b) of this Section. 
 (b) The
Borrower shall notify the Administrative Agent by telephone (confirmed by hand delivery, fax or emailed pdf) of any prepayment under Section 2.11(a) not later than 11:00 a.m., New York City time on the date of prepayment. Each such
notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, any such notice of prepayment may be conditioned upon the effectiveness of other
credit facilities or another event. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Term Lenders of the contents thereof. Each partial prepayment of any Borrowing under
Section 2.11(a) shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be
accompanied by accrued interest to the extent required by Section 2.13. 
 Section 2.12 Fees. 

(a) The Borrower agrees to pay to the Administrative Agent for the account of each Term Lender (other than a Defaulting Lender) a commitment
fee on the daily average unused amount of the Commitment of such Term Lender during the Availability Period at the Applicable Rate for commitment fees. Accrued commitment fees shall be payable on the last day of the Availability Period. All
commitment fees shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 

(b) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent. Fees paid shall
not be refundable under any circumstances. 
 (c) Anything herein to the contrary notwithstanding, during such period as a Term Lender is a
Defaulting Lender, such Defaulting Lender will not be entitled to any fees accruing during such period pursuant to this Section 2.12 (without prejudice to the rights of the Term Lenders other than Defaulting Lenders in respect of such
fees) nor shall any such fee be payable by the Borrower. 
 Section 2.13 Interest. 

(a) The Loans comprising each ABR Borrowing shall bear interest on each day at the Alternate Base Rate for such day plus the Applicable Rate.

 (b) The Loans comprising each Eurodollar Borrowing shall bear interest at the LIBO Rate for the Interest Period in effect for such
Borrowing plus the Applicable Rate. 
 (c) [Reserved]. 

(d) Notwithstanding the foregoing, upon the occurrence and during the continuance of any Event of Default, if any principal of or interest on
any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or 

  
 30 








 
otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate
otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section. 

(e) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and on the Maturity Date;
provided that (i) interest accrued pursuant to paragraph (d) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end of
the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current
Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. 
 (f) All interest
determined by reference to the LIBO Rate or clauses (b) or (c) of the definition of Alternate Base Rate shall be computed on the basis of a year of 360 days, and all other interest shall be computed on the basis of a year of 365 days (or
366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate or LIBO Rate shall be determined by the Administrative Agent,
and such determination shall be conclusive absent manifest error. 
 (g) The Borrower shall pay to each Term Lender, so long as such Term
Lender shall be required under regulations of the Board of Governors of the Federal Reserve System of the United States of America to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities,
additional interest on the unpaid principal amount of each Borrowing of such Term Lender during such periods as such Borrowing is a Eurodollar Borrowing, from the date of such Borrowing until such principal amount is paid in full, at an interest
rate per annum equal at all times to the remainder obtained by subtracting (i) the LIBO Rate for the Interest Period in effect for such Eurodollar Borrowing from (ii) the rate obtained by dividing such LIBO Rate by a percentage equal to
100% minus the Eurodollar Rate Reserve Percentage of such Term Lender for such Interest Period. Such additional interest shall be determined by such Term Lender. The Borrower shall from time to time, within 15 days after demand (which demand shall
be accompanied by a certificate comporting with the requirements set forth in Section 2.15(c)) by such Term Lender (with a copy of such demand and certificate to the Administrative Agent) pay to the Term Lender giving such notice such
additional interest; provided, however, that Borrower shall not be required to pay to such Term Lender any portion of such additional interest that accrued more than 90 days prior to any such demand, unless such additional interest was
not determinable on the date that is 90 days prior to such demand. 
 Section 2.14 Alternate Rate of Interest. If prior to
the commencement of any Interest Period for a Eurodollar Borrowing: 
 (a) the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the LIBO Rate, as applicable, for such Interest Period; or 

  
 31 








 (b) the Administrative Agent is advised by the Required Lenders that the LIBO Rate, as
applicable, for such Interest Period will not adequately and fairly reflect the cost to such Term Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period; 

then the Administrative Agent shall give notice thereof to the Borrower and the Term Lenders by telephone or telecopy as promptly as practicable thereafter
and, until the Administrative Agent notifies the Borrower and the Term Lenders that the circumstances giving rise to such notice no longer exist, any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any
Borrowing as, a Eurodollar Borrowing shall be ineffective. 
 Section 2.15 Increased Costs. 

(a) Increased Costs Generally. If any Change in Law shall: 

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement
against assets of, deposits with or for the account of, or credit extended or participated in by, any Term Lender; 
 (ii)
subject any Recipient to any Tax of any kind whatsoever with respect to this Agreement or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Recipient in respect thereof (except for any Indemnified Taxes and the
imposition of, or any change in the rate of, any Tax described in clauses (a)(ii) through (d) of the definition of Excluded Taxes payable by such Recipient); or 

(iii) impose on any Term Lender or the London interbank market any other condition, cost or expense affecting this Agreement or
Eurodollar Loans made by such Term Lender; 
 and the result of any of the foregoing shall be to increase the cost to such Term Lender of making, funding or
maintaining any Loan (or of maintaining its obligation to make any such Loan), or to reduce the amount of any sum received or receivable by such Term Lender hereunder (whether of principal, interest or any other amount) then, upon request of such
Term Lender, the Borrower will pay to such Term Lender such additional amount or amounts as will compensate such Term Lender for such additional costs incurred or reduction suffered, in each case to the extent applicable to the Loans. 

(b) Capital Requirements. If any Term Lender determines that any Change in Law affecting such Term Lender or any lending office of such
Term Lender or such Term Lender’s holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Term Lender’s capital or on the capital of such Term Lender’s
holding company, if any, as a consequence of this Agreement, the commitments of such Term Lender or the Loans made by, to a level below that which such Term Lender or such Term Lender’s holding company could have achieved but for such Change in
Law (taking into consideration such Term Lender’s policies and the policies of such Term Lender’s holding company with respect to capital adequacy or liquidity), then from time to time the Borrower will pay to such Term Lender such
additional amount or amounts as will compensate such Term Lender or such Term Lender’s holding company for any such reduction suffered, in each case to the extent applicable to the Loans. 

  
 32 








 (c) Certificates for Reimbursement. A certificate of a Term Lender setting forth the
amount or amounts necessary to compensate such Term Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section, showing the computation thereof and delivered to the Borrower shall be conclusive
absent manifest error. Such certificate shall further certify that such Term Lender is making similar demands of its other similarly situated borrowers. The Borrower shall pay such Term Lender the amount shown as owed by it and due on any such
certificate within 10 days after receipt thereof. 
 (d) Delay in Requests. Failure or delay on the part of any Term Lender to demand
compensation pursuant to this Section shall not constitute a waiver of such Term Lender’s right to demand such compensation, provided that Borrower shall not be required to compensate a Term Lender pursuant to this Section for any
increased costs incurred or reductions suffered more than ninety days prior to the date that such Term Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Term Lender’s intention to
claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the ninety day period referred to above shall be extended to include the period of retroactive effect thereof).

 Section 2.16 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than
on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to
borrow, convert, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is revoked in accordance therewith), or (d) the
assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.19, then, in any such event, the Borrower shall compensate each Term
Lender for the loss, cost and expense (excluding loss of anticipated profits) attributable to such event. A certificate of any Term Lender setting forth, in reasonable detail showing the computation thereof, any amount or amounts that such Lender is
entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Term Lender the amount shown as due on any such certificate within 10 days after receipt
thereof, if such certificate complies herewith. 
 Section 2.17 Taxes. 

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan
Document shall be made free and clear of and without reduction or withholding for any Taxes, provided that if an applicable withholding agent shall be required by applicable law to deduct or withhold any Taxes from such payments, then
(i) if such Tax is an Indemnified Tax, the sum payable by the Borrower shall be increased as necessary so that after making all required deductions or withholdings (including deductions applicable to additional sums payable under this Section)
the applicable Recipient receives an amount equal to the sum it would have received had no such deductions or withholdings been made, (ii) the applicable withholding agent shall make such deductions and (iii) such withholding agent shall
timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 

  
 33 








 (b) Payment of Other Taxes by Borrower. Without limiting the provisions of paragraph
(a) above, the Borrower shall timely pay any Other Taxes related to it to the relevant Governmental Authority in accordance with applicable law. 

(c) Indemnification by Borrower. The Borrower shall indemnify each Recipient within 10 days after demand therefor, for the full amount
of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment
to such Recipient and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental
Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Recipient (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Recipient shall be
conclusive absent manifest error. 
 (d) Indemnification by the Term Lenders. Each Term Lender shall severally indemnify the
Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Term Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes
and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Term Lender’s failure to comply with the provisions of Section 9.05(d) relating to the maintenance of a Participant Register and
(iii) any Excluded Taxes attributable to such Term Lender, in each case, that are payable or paid by the Administrative Agent in connection with the Borrower, and any reasonable expenses arising therefrom or with respect thereto, whether or not
such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Term Lender by the Administrative Agent shall be conclusive absent manifest
error. Each Term Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Term Lender under any Loan Document or otherwise payable by the Administrative Agent to the Term Lender from any
other source against any amount due to the Administrative Agent under this paragraph (d). 
 (e) Evidence of Payments. As soon as
practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority pursuant to this Section 2.17, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 

(f) Status of Term Lenders. 

(i) Any Term Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under
any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation
prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Term Lender, if


  
 34 








 
requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable requirement of law or reasonably requested by the Borrower or the
Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Term Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the
preceding two sentences, the completion, execution and submission of such documentation (other than such documentation either set forth in Section 2.17(f)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the
Term Lender’s reasonable judgment such completion, execution or submission would subject such Term Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Term Lender. 

(ii) Without limiting the generality of the foregoing, 

(A) any Term Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on
which such Term Lender becomes a Term Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Term Lender is
exempt from U.S. Federal backup withholding Tax; 
 (B) any Foreign Lender shall deliver to the Borrower and the
Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Term Lender under this Agreement (and from time to time thereafter upon the reasonable request of
the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable: (i) in the case of a Foreign Lender claiming the benefits of an income Tax treaty to which the
United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN or IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the
“interest” article of such Tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN or IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. Federal withholding Tax
pursuant to the “business profits” or “other income” article of such Tax treaty; (ii) executed originals of IRS Form W-8ECI; (iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio
interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit F-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a
“10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance
Certificate”) and (y) executed originals of IRS Form W-8BEN or IRS Form W-8BEN-E; or (iv) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form
W-8BEN or IRS Form W-8BEN-E, a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3, IRS Form W-9, and/or other certification documents from 

  
 35 








 
each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio
interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on behalf of each such direct and indirect partner; 

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative
Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the
Administrative Agent), executed originals of any other form prescribed by an applicable law as a basis for claiming exemption from or a reduction in U.S. Federal withholding Tax, duly completed, together with such supplementary documentation as may
be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and 

(D) if a payment made to a Term Lender under any Loan Document would be subject to any withholding Tax imposed by FATCA if such
Term Lender were to fail to comply with the requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code), such Term Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed
by law and at such time or times reasonably requested by the Borrower or the Administrative Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional
documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA, to determine that such Term Lender has or has not complied
with such Term Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this
Agreement. 
 Each Term Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it
shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so. 

(g) Treatment of Certain Refunds. If any Recipient determines in its sole discretion exercised in good faith, that it has received a
refund of any Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid pursuant to this Section 2.17 (including by the payment of additional amounts pursuant to this
Section 2.17), such Recipient shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid by the Borrower under this Section with respect to the Taxes giving
rise to such refund), net of reasonable out-of-pocket expenses directly related to the receipt of such refund by the Recipient and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund)
provided that, the Borrower, upon the request of such Recipient, agrees to repay the amount paid over to the Borrower pursuant to this paragraph (g) (plus any penalties, interest or other charges imposed by the relevant Governmental


  
 36 








 
Authority) to the Recipient in the event the Recipient is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (g), in no event
will the applicable Recipient be required to pay any amount to the Borrower pursuant to this paragraph (g) the payment of which would place such Recipient in a less favorable net after-Tax position than the Recipient would have been in if the
indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph shall not be construed to require the Administrative Agent or any Term Lender to make available its Tax returns (or any other information
relating to its Taxes that it deems confidential) to the Borrower or any other Person. 
 (h) [Reserved.] 

(i) Survival. Each party’s obligations under this Section 2.17 shall survive the resignation or replacement of the
Administrative Agent or any assignment of rights by, or the replacement of, a Term Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document. 

Section 2.18 Payments Generally; Pro Rata Treatment; Sharing of Set-offs. 

(a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, or fees, or of amounts payable
under Section 2.15, 2.16 or 2.17, or otherwise) prior to 1:00 p.m., New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date
may, in the discretion of the Administrative Agent, be deemed to have been received on the date of such payment or on the next succeeding Business Day for purposes of calculating interest and fees thereon. All such payments shall be made to the
Administrative Agent at its offices at Barclays Bank PLC, 745 Seventh Avenue, New York, NY 10019, Attention: U.S. Loan Operations. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the
appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing
interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars. 
 (b) If at
any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then
due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto
in accordance with the amounts of principal then due to such parties. 
 (c) If any Term Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Term Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than
the proportion received by any other Term Lender, then the Term Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such
payments shall be shared by the Term Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are purchased


  
 37 








 
and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest,
and (ii) the provisions of this Section 2.18(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Term Lender as
consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The
Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Term Lender acquiring a participation pursuant to this subsection (c) may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Term Lender were a direct creditor of the Borrower in the amount of such participation. 

(d) [Reserved]. 
 (e) If any
Lender shall fail to make any payment required to be made by it pursuant to Sections 2.07(b) or 9.04(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter
received by the Administrative Agent for the account of such Term Lender to satisfy such Term Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. In the event that any Defaulting Lender exercises any
such right of setoff, (x) all amounts so set off will be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Sections 2.07(b) or 9.04(c), and, pending such payment, will
be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent and the Term Lenders and (y) the Defaulting Lender will provide promptly to the Administrative Agent a statement
describing in reasonable detail the obligations owing to such Defaulting Lender as to which it exercised such right of setoff. 

Section 2.19 Mitigation Obligations; Replacement of Term Lenders. 

(a) If any Term Lender requests compensation under Section 2.13(g) or Section 2.15 or if the Borrower is required
to pay any Indemnified Taxes to any Term Lender or any Governmental Authority for the account of any Term Lender, then such Term Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder
or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Term Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Sections
2.13(g), 2.15 or 2.17, as the case may be, in the future and (ii) would not subject such Term Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Term Lender. If the Borrower is
required to make any payment under Sections 2.13(g), 2.15 or 2.17, the Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Term Lender in connection with any such designation or assignment. Subject to
the foregoing, Term Lenders agree to use reasonable efforts to select lending offices which will minimize Indemnified Taxes and other costs and expenses for the Borrower. 

(b) If any Term Lender requests compensation under Section 2.13(g) or Section 2.15, or if the Borrower is required to
pay any Indemnified Taxes to any Term Lender or any Governmental Authority for the account of any Term Lender pursuant to Section 2.17, or if any Term Lender is a Defaulting Lender, or if any Term Lender fails to approve an amendment,
waiver or other 

  
 38 








 
modification to this Agreement that requires the approval of all Term Lenders and at least the Required Lenders have approved such amendment, waiver or other modification, then the Borrower may,
at its sole expense and effort, upon notice to such Term Lender and the Administrative Agent, require such Term Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in
Section 9.05), all its interests, rights and obligations under this Agreement to an Eligible Assignee that shall assume such obligations (which assignee may be another Term Lender, if a Term Lender accepts such assignment);
provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld or delayed, (ii) such Term Lender shall have received payment of an amount
equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 2.16), from the assignee (to
the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.13(g) or
Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments. A Term Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Term Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. If any Term Lender refuses to assign and delegate all its
interests, rights and obligations under this Agreement after the Borrower has required such Term Lender to do so as a result of a claim for compensation under Section 2.13(g) or Section 2.15 or payments required to be made
pursuant to Section 2.17, such Term Lender shall not be entitled to receive such compensation or required payments. 
 (c) If
the Borrower and the Administrative Agent agree in writing in their discretion that a Term Lender that is a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon
as of the effective date specified in such notice and subject to any conditions set forth therein, such Term Lender will, to the extent applicable, purchase such portion of outstanding Loans of the other Term Lenders and/or make such other
adjustments as the Administrative Agent may determine to be necessary to cause the Credit Exposure of the Term Lenders to be on a pro rata basis in accordance with their respective Commitments, whereupon such Term Lender will cease to be a
Defaulting Lender and will be a Non-Defaulting Lender (and such Credit Exposure of each Term Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided that no adjustments will be made retroactively with
respect to fees accrued or payments made by or on behalf of the Borrower while such Term Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder
from Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Term Lender having been a Defaulting Lender.

in, and (if applicable) is in good standing in, every jurisdiction where such qualification is required, except where the failure to do so or to be validly existing and in good standing or to have such power and authority, individually or in the
aggregate, would not reasonably be expected to result in a Material Adverse Effect. 
 Section 3.02 Authorization;
Enforceability. The Transactions and the performance of its obligations contemplated thereby are within the Borrower’s partnership powers, and have been duly authorized by all necessary partnership and, if required, partner action, as
applicable. This Agreement has been duly executed and delivered by the Borrower and constitutes a legal, valid and binding obligation of the Borrower, enforceable against the Borrower in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 

Section 3.03 Governmental Approvals; No Conflicts. No material authorization or approval or other action by, and no notice to or
filing with, any Governmental Authority is required for the due execution, delivery and performance by the Borrower of any Loan Document to which it is a party, or the consummation of the transactions contemplated thereby. The execution, delivery
and performance by the Borrower of the Loan Documents to which it is shown as being a party and the consummation of the transactions contemplated thereby do not contravene (a) the Borrower’s organizational documents or (b) any law or
any restriction under any material agreement binding on the Borrower and will not result in or require the creation or imposition of any Lien prohibited by this Agreement.

quarterly reports on Form 10-Q or current reports on Form 8-K filed subsequent thereto but prior to the Effective Date, or any amendments thereof filed subsequent thereto but prior to the Effective Date, in each case of the Borrower, there are no
actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Borrower, threatened in writing against the Borrower or any of its Subsidiaries (i) as to which there is a
reasonable possibility of an adverse determination and that would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or (ii) that purport to adversely affect the legality, validity and
enforceability of the Loan Documents and are non-frivolous (as reasonably determined by the Administrative Agent); provided, that this representation, when made, shall not constitute an admission that any action, suit or proceeding set 

  
 40 








 
forth in any annual report on Form 10-K, any quarterly report on Form 10-Q, any current report on Form 8-K or any amendments to any of the foregoing, in each case referred to above would result
in a Material Adverse Effect due to an adverse determination, if any. 
 Section 3.06 Environmental Matters. Except as set forth
in the annual report on Form 10-K for the year ended December 31, 2014, the quarterly reports on Form 10-Q or current reports on Form 8-K filed subsequent thereto but prior to the Effective Date, or any amendments thereof filed subsequent
thereto but prior to the Effective Date, in each case of the Borrower, the Borrower and its Subsidiaries have reasonably concluded that they: (a) are in compliance with all applicable Environmental Laws, except to the extent that any
non-compliance would not reasonably be expected to have a Material Adverse Effect with respect to the Borrower; (b) are not subject to any judicial, administrative, government, regulatory or arbitration proceeding alleging the violation of any

authorizations which are necessary under any applicable Environmental Laws to conduct their business, except to the extent that the failure to possess, or be in compliance with, any of the foregoing would not reasonably be expected to have a
Material Adverse Effect with respect to the Borrower. 
 Section 3.07 Disclosure. As of the Effective Date only, none of the
reports, financial statements, certificates or other written information furnished by or on behalf of the Borrower in connection with the Transactions to the Administrative Agent or any Term Lender on or prior to the Effective Date (as modified or
supplemented by other information so furnished on or prior to the Effective Date), taken as a whole, contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not materially misleading, provided that, with respect to any projected financial information, the Borrower represents only that such information was prepared in good faith based upon assumptions
believed by the Borrower to be reasonable at the time (it being recognized, however, that projections as to future events are not to be viewed as facts and that the actual results during the period or periods covered by any projections may
materially differ from the projected results).

the Transactions (including each Loan) to be consummated on such date, the Borrower, individually and together with its Subsidiaries, is Solvent. 

Section 3.09 ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such

company” as defined in, or subject to regulation under, the Investment Company Act of 1940.

State Department, the United Nations Security Council, the European Union, Her Majesty’s Treasury, or other relevant sanctions authority (collectively, “Sanctions”); none of the Borrower or any of its Subsidiaries is located,
organized or resident in a country or territory that is, or whose government is, the subject of Sanctions. 
 (b) No any part of the
proceeds of the Loans will be used, directly or, to the knowledge of the Borrower, indirectly, (i) to fund or finance any activities or business of or with any Person or vessel, or in any country or territory, that, at the time of such funding
or financing, is, or whose government is, the subject of Sanctions if such activities or business would be prohibited for a U.S. Person pursuant to Sanctions, or (ii) in any other manner that would result in a violation of Sanctions by the
Borrower or any Subsidiary or any other party to this Agreement. 
 (c) The Borrower and its Subsidiaries are in compliance with all
applicable anti-corruption laws, including the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (the “FCPA”), except for such non-compliance that could not, based upon the facts and
circumstances existing at the time, reasonably be expected to (x) result in a Material Adverse Effect or (y) result in material liability to any Term Lender or the Administrative Agent. Williams has instituted and maintains policies and
procedures reasonably designed to promote compliance by the Borrower with the FCPA and all other applicable anti-corruption laws, and the Borrower adheres to such policies and procedures. No part of the proceeds of the Loans will be used, directly
or, to the knowledge of the Borrower, indirectly, in violation of the FCPA or any other applicable anti-corruption law, including for any payments to any governmental official or employee, political party, official of a political party, candidate

Combination shall be not lower than the rating by Moody’s or S&P, 

  
 48

an amount referred to in clause (a) or (b)(i) of this Article) payable under this Agreement, when and as the same shall become due and payable, and such failure shall continue unremedied for a period of ten (10) days;

continue after the applicable grace period, if any, specified in the agreement or instrument relating to such Material Indebtedness or such Hedging Agreements; or (ii) default in the observance or performance of any covenant or obligation
contained in any agreement of such Material Indebtedness or the Existing Credit Agreement or, in either case, any Refinanced Indebtedness in respect thereof, that is a default (in each case, other than a failure to pay specified in clause
(i) of this subsection (f)) and such default shall continue after the applicable grace period, if any, specified in such agreement or instrument, if the effect thereof is to accelerate the maturity of such Material Indebtedness or require such

against the Borrower or any Material Subsidiary of the Borrower or any combination thereof and the same shall remain undischarged for a period of 30 consecutive days during which execution shall not be effectively stayed, or any action shall be
legally taken by a judgment creditor to attach or levy upon any assets of the Borrower or any such Material Subsidiary of the Borrower to enforce any such judgment; 

(k) an ERISA Event shall have occurred and, thirty (30) days after notice thereof shall have been given to the Borrower by the
Administrative Agent, such ERISA Event shall still exist, and such ERISA Event, when taken together with all other ERISA Events that have occurred, would reasonably be expected to result in a Material Adverse Effect; 

(l) the Borrower or any Material Subsidiary or ERISA Affiliate of the Borrower shall have been notified by the sponsor of a Multiemployer Plan
that it has incurred Withdrawal Liability to such Multiemployer Plan in an amount which, when aggregated with all other amounts required to be paid to Multiemployer Plans in connection with Withdrawal Liabilities (determined as of the date of such
notification), would reasonably be expected to result in a Material Adverse Effect; 

  
 53 








 (m) the Borrower or any Material Subsidiary or ERISA Affiliate of the Borrower shall have been
notified by the sponsor of a Multiemployer Plan that such Multiemployer Plan is in reorganization or is being terminated, within the meaning of Title IV of ERISA, if as a result of such reorganization or termination the aggregate annual
contributions of the Borrower and its ERISA Affiliates to all Multiemployer Plans which are then in reorganization or being terminated have been or will be increased over the amounts contributed to such Multiemployer Plans for the respective plan
years which include the Effective Date by an amount that would reasonably be expected to result in a Material Adverse Effect; 
 (n) the
General Partner takes, suffers or permits to exist any of the events or conditions referred to in clauses (g), (h) or (i) of this Article; 

(o) a Change in Control shall occur; or 

(p) if any Guaranty of a Material Subsidiary is required to be in effect pursuant to Section 5.09(a) and prior to the release of
such Guaranty pursuant to Section 5.09(b), (i) such Guaranty for any reason is not a legal, valid, binding and enforceable obligation of such Guarantor party thereto for more than five (5) days or (ii) such Guarantor shall
so state in writing that such Guaranty for any reason is not a legal, valid, binding and enforceable obligation of such Guarantor; 
 then, and in every
such event (other than an event with respect to the Borrower described in clause (g) or (h) of this Article), and at any time thereafter during the continuance of such event, the Administrative Agent at the request of the Required Lenders
shall, by notice to the Borrower, take any of the following actions, at the same or different times: (i) declare the Loans owed by the Borrower as to which an Event of Default has occurred and is continuing to be due and payable in whole
(or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and
all fees and other obligations of the Borrower accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower; and in case of any event
with respect to the Borrower described in clause (g) or (h) of this Article, the obligations of each Lender to make Loans to the Borrower shall be automatically terminated and the principal of the Loans of the Borrower then outstanding,
together with accrued interest thereon and all fees and other obligations owed by the applicable Borrower as to which such Event of Default has occurred and is continuing, shall automatically become due and payable, without presentment, demand,
protest or other notice of any kind, all of which are hereby waived by the Borrower, and (ii) exercise on behalf of itself and the Term Lenders all rights and remedies available to it and the Term Lenders under the Loan Documents. 

ARTICLE VIII 
 THE
ADMINISTRATIVE AGENT 
 Section 8.01 Appointment and Authority. Each Term Lender hereby irrevocably appoints Barclays Bank
PLC to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by
the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent and the Term Lenders, and no Borrower or Guarantor shall
have rights as a third party beneficiary of any of such provisions. 

  
 54 








 Section 8.02 Administrative Agent Individually. 

(a) The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Term Lender as any
other Term Lender and may exercise the same as though it were not the Administrative Agent and the term “Term Lender” or “Term Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include
the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in
any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Term Lenders. 

(b) Each Term Lender understands that the Person serving as Administrative Agent, acting in its individual capacity, and its Affiliates
(collectively, the “Agent’s Group”) are engaged in a wide range of financial services and businesses (including investment management, financing, securities trading, corporate and investment banking and research) (such services
and businesses are collectively referred to in this Article VIII as “Activities”) and may engage in the Activities with or on behalf of one or more of the Borrower or their respective Affiliates. Furthermore, the Agent’s
Group may, in undertaking the Activities, engage in trading in financial products or undertake other investment businesses for its own account or on behalf of others (including the Borrower and its Affiliates and including holding, for its own
account or on behalf of others, equity, debt and similar positions in the Borrower or its Affiliates), including trading in or holding long, short or derivative positions in securities, loans or other financial products of one or more of the
Borrower or its Affiliates. Each Term Lender understands and agrees that in engaging in the Activities, the Agent’s Group may receive or otherwise obtain information concerning the Borrower or its Affiliates (including information concerning
the ability of the Borrower to perform its obligations hereunder and under the other Loan Documents) which information may not be available to any of the Term Lenders that are not members of the Agent’s Group. None of the Administrative Agent
nor any member of the Agent’s Group shall have any duty to disclose to any Term Lender or use on behalf of the Term Lenders, and shall not be liable for the failure to so disclose or use, any information whatsoever about or derived from the
Activities or otherwise (including any information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of the Borrower or any Affiliate thereof) or to account for any revenue or profits
obtained in connection with the Activities, except that the Administrative Agent shall deliver or otherwise make available to each Term Lender such documents as are expressly required by any Loan Document to be transmitted by the Administrative
Agent to the Term Lenders. 
 (c) Each Term Lender further understands that there may be situations where members of the Agent’s Group
or their respective customers (including the Borrower and its Affiliates) either now have or may in the future have interests or take actions that may conflict with the interests of any one or more of the Term Lenders (including the interests of the
Lenders hereunder and under the other Loan Documents). Each Term Lender agrees that no member of the Agent’s Group is or shall be required to restrict its activities as a result of the Person serving as Administrative Agent being a member of
the Agent’s Group, and that each member of the Agent’s Group may undertake any 

  
 55 








 
Activities without further consultation with or notification to any Term Lender. None of (i) this Agreement nor any other Loan Document, (ii) the receipt by the Agent’s Group of
information (including Information) concerning the Borrower or its Affiliates (including information concerning the ability of the Borrower to perform their respective obligations hereunder and under the other Loan Documents) nor (iii) any
other matter shall give rise to any fiduciary, equitable or contractual duties (including without limitation any duty of trust or confidence) owing by the Administrative Agent or any member of the Agent’s Group to any Term Lender including any
such duty that would prevent or restrict the Agent’s Group from acting on behalf of customers (including the Borrower or its Affiliates) or for its own account. 

Section 8.03 Duties of Administrative Agent; Exculpatory Provisions. 

(a) The Administrative Agent’s duties hereunder and under the other Loan Documents are solely ministerial and administrative in nature
and the Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Administrative Agent shall not have any duty to take
any discretionary action or exercise any discretionary powers, but shall be required to act or refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the written direction of the Required Lenders (or such
other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its
counsel, may expose the Administrative Agent or any of its Affiliates to liability or that is contrary to any Loan Document or applicable law, including, for the avoidance of doubt, any action that may be in violation of the automatic stay under the
Bankruptcy Code or other debtor relief law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of the Bankruptcy Code or other debtor relief law. 

(b) The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the
Required Lenders (or such other number or percentage of the Term Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 9.03 or
Article VII) or (ii) in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default or the event or events that give or may give rise to any Default unless
and until the Borrower or any Term Lender shall have given notice to the Administrative Agent describing such Default and such event or events. 

(c) Neither the Administrative Agent nor any member of the Agent’s Group shall be responsible for or have any duty to ascertain or
inquire into (i) any statement, warranty, representation or other information made or supplied in or in connection with this Agreement, any other Loan Document, (ii) the contents of any certificate, report or other document delivered
hereunder or thereunder or in connection herewith or therewith or the adequacy, accuracy and/or completeness of the information contained therein, (iii) the performance or observance of any of the covenants, agreements or other terms or
conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the
satisfaction of any condition set forth in Article IV or elsewhere herein, other than (but subject to the foregoing clause (ii)) to confirm receipt of items expressly required to be delivered to the Administrative Agent. 

  
 56 








 (d) Nothing in this Agreement or any other Loan Document shall require the Administrative Agent
or any of its Related Parties to carry out any “know your customer” or other checks in relation to any person on behalf of any Term Lender and each Term Lender confirms to the Administrative Agent that it is solely responsible for any such
checks it is required to carry out and that it may not rely on any statement in relation to such checks made by the Administrative Agent or any of its Related Parties. 

Section 8.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and
to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any
liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, that by its terms must be fulfilled to the satisfaction of a Term Lender, the Administrative Agent may presume that such condition is
satisfactory to such Term Lender unless an officer of the Administrative Agent responsible for the transactions contemplated hereby shall have received notice to the contrary from such Term Lender prior to the making of such Loan, and in the case of
a Borrowing, such Term Lender shall not have made available to the Administrative Agent such Term Lender’s ratable portion of such Borrowing. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower),
independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 

Section 8.05 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and
powers hereunder or under any other Loan Document by or through any one or more sub agents appointed by the Administrative Agent. The Administrative Agent and any such sub agent may perform any and all of its duties and exercise its rights and
powers by or through their respective Related Parties. Each such sub agent and the Related Parties of the Administrative Agent and each such sub agent shall be entitled to the benefits of all provisions of this Article VIII and
Section 9.04 (as though such sub-agents were the “Administrative Agent” under the Loan Documents) as if set forth in full herein with respect thereto. The Administrative Agent shall not be responsible for the negligence or
misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub
agents. 
 Section 8.06 Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its
resignation to the Term Lenders and the Borrower (such notice not to be effective until 30 days have lapsed). Upon receipt of any such notice of resignation, the Required Lenders shall have the right, unless an Event of Default under subsection (a),
(g) or (h) of Article VII has occurred and is continuing, with the consent of the Borrower, to appoint a successor. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment
within 30 days after the retiring Administrative Agent gives notice of its resignation (such 30-day period, the “Lender Appointment Period”), then the retiring Administrative Agent may on behalf of the Term Lenders, appoint a
successor Administrative Agent meeting the qualifications set forth above. In addition and without any obligation on the part of the retiring Administrative 

  
 57 








 
Agent to appoint, on behalf of the Term Lenders, a successor Administrative Agent, the retiring Administrative Agent may at any time upon or after the end of the Lender Appointment Period notify
the Borrower and the Term Lenders that no qualifying Person has accepted appointment as successor Administrative Agent and the effective date of such retiring Administrative Agent’s resignation which effective date shall be no earlier than
three business days after the date of such notice. Upon the resignation effective date established in such notice and regardless of whether a successor Administrative Agent has been appointed and accepted such appointment, the retiring
Administrative Agent’s resignation shall nonetheless become effective and (i) the retiring Administrative Agent shall be discharged from its duties and obligations as Administrative Agent hereunder and under the other Loan Documents and
(ii) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Term Lender directly, until such time as the Required Lenders appoint a successor
Administrative Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and
duties as Administrative Agent of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations as Administrative Agent hereunder or under the other Loan Documents
(if not already discharged therefrom as provided above in this paragraph). The fees payable by WPZ to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between WPZ and such successor.
After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 9.04 shall continue in effect for the benefit of such retiring Administrative Agent, its
sub agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent. Anything herein to the contrary notwithstanding, if at
any time the Required Lenders determine that the Person serving as Administrative Agent is (without taking into account any provision in the definition of “Defaulting Lender” requiring notice from the Administrative Agent or any other
party) a Defaulting Lender, the Required Lenders (determined after giving effect to Section 9.03) may by notice to the Borrower and such Person remove such Person as Administrative Agent and, in with the consent of the Borrower, appoint
a replacement Administrative Agent hereunder. Such removal will, to the fullest extent permitted by applicable law, be effective on the earlier of (i) the date a replacement Administrative Agent is appointed and (ii) the date 30 days after
the giving of such notice by the Required Lenders (regardless of whether a replacement Administrative Agent has been appointed). 

Section 8.07 Non-Reliance on Administrative Agent and Other Term Lenders. 

(a) Each Term Lender confirms to the Administrative Agent, each other Term Lender and each of their respective Related Parties that it
(i) possesses (individually or through its Related Parties) such knowledge and experience in financial and business matters that it is capable, without reliance on the Administrative Agent, any other Term Lender or any of their respective
Related Parties, of evaluating the merits and risks (including Tax, legal, regulatory, credit, accounting and other financial matters) of (x) entering into this Agreement, (y) making Loans and other extensions of credit hereunder and under
the other Loan Documents and (z) taking or not taking actions hereunder and thereunder, (ii) is financially able to bear such risks and (iii) has determined that entering into this Agreement and making Loans and other extensions of
credit hereunder and under the other Loan Documents is suitable and appropriate for it.

consent and other communication shall have been made generally available on such Approved Electronic Platform, Internet website or similar device to the class of Person being notified (regardless of whether any such Person must accomplish, and
whether or not any such Person shall have accomplished, any action prior to obtaining access to such items, including registration, disclosure of contact information, compliance with a standard user agreement or undertaking a duty of

 (c) Notwithstanding clauses (a) and (b) (unless the
Administrative Agent requests that the provisions of clause (a) and (b) be followed) and any other provision in this Agreement or any other Loan Document providing for the delivery of any Approved Electronic Communication by any other
means, the Borrower shall deliver all Approved Electronic Communications to the Administrative Agent by properly transmitting such Approved Electronic Communications in an electronic/soft medium in a format acceptable to the Administrative Agent to
xrausloanops@barclays.com or such other electronic mail address (or similar means of electronic delivery) as the Administrative Agent may notify to the Borrower. Nothing in this clause (c) shall prejudice the right of the Administrative
Agent or any Term Lender to deliver any Approved Electronic Communication to the Borrower in any manner authorized in this Agreement or to request that the Borrower effect delivery in such manner. 

Section 9.02 Posting of Approved Electronic Communications. 

(a) Each of the Term Lenders and the Borrower agree that the Administrative Agent may, but shall not be obligated to, make the Approved
Electronic Communications available to the Term Lenders by posting such Approved Electronic Communications on Debt Domain or a substantially similar electronic platform chosen by the Administrative Agent to be its electronic transmission system (the
“Approved Electronic Platform”). 

  
 60 








 (b) Although the Approved Electronic Platform and its primary web portal are secured with
generally-applicable security procedures and policies implemented or modified by the Administrative Agent from time to time, each of the Term Lenders and the Borrower acknowledges and agrees that the distribution of material through an electronic
medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution. In consideration for the convenience and other benefits afforded by such distribution and for the other consideration provided
hereunder, the receipt and sufficiency of which are hereby acknowledged, each of the Term Lenders and the Borrower hereby approves distribution of the Approved Electronic Communications through the Approved Electronic Platform and understands and
assumes the risks of such distribution. 
 (c) THE APPROVED ELECTRONIC PLATFORM AND THE APPROVED ELECTRONIC COMMUNICATIONS ARE PROVIDED
“AS IS” AND “AS AVAILABLE”. NONE OF THE ADMINISTRATIVE AGENT NOR ANY OTHER MEMBER OF THE AGENT’S GROUP WARRANT THE ACCURACY, ADEQUACY OR COMPLETENESS OF THE APPROVED ELECTRONIC COMMUNICATIONS OR THE APPROVED ELECTRONIC
PLATFORM AND EACH EXPRESSLY DISCLAIMS ANY LIABILITY FOR ERRORS OR OMISSIONS IN THE APPROVED ELECTRONIC COMMUNICATIONS OR THE APPROVED ELECTRONIC PLATFORM. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY
WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN CONNECTION WITH THE APPROVED ELECTRONIC COMMUNICATIONS OR THE
APPROVED ELECTRONIC PLATFORM. 
 (d) Each of the Term Lenders and the Borrower agree that the Administrative Agent may, but (except as may
be required by applicable law) shall not be obligated to, store the Approved Electronic Communications on the Approved Electronic Platform in accordance with the Administrative Agent’s generally-applicable document retention procedures and
policies. 
 Section 9.03 Waivers; Amendments. 

(a) No failure or delay by the Administrative Agent or any Term Lender in exercising any right or power hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power.
The rights and remedies of the Administrative Agent and the Term Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any
departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for
which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent or any Term Lender may have had notice or knowledge of such Default
at the time. 

  
 61 








 (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except
pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall
(i) increase or extend the Commitment of any Term Lender without the written consent of such Term Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without
the written consent of each Term Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any
such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Term Lender affected thereby, (iv) except as contemplated in Section 2.04(e), change any provision in a manner that
would alter the pro rata sharing of payments required thereby, without the written consent of each Term Lender, or (v) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof
specifying the number or percentage of Term Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Term Lender; provided further that no
such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder without the prior written consent of the Administrative Agent. Except as provided herein, during such period as a Term Lender is a
Defaulting Lender, to the fullest extent permitted by applicable law, such Term Lender will not be entitled to vote in respect of amendments and waivers hereunder and the Applicable Percentage and the outstanding Loans of such Term Lender hereunder
will not be taken into account in determining whether the Required Lenders or all of the Term Lenders, as required, have approved any such amendment or waiver (and the definition of “Required Lenders” will automatically be deemed modified
accordingly for the duration of such period); provided, that any such amendment or waiver referred to in clauses (i) through (v) or the proviso above or that would alter the terms of this proviso shall require the consent of such
Defaulting Lender to the extent such Defaulting Lender is affected thereby. 
 (c) Notwithstanding the foregoing, the Administrative Agent
and WPZ may amend any Loan Document to correct any obvious errors, mistakes, omissions, defects or inconsistencies of a technical or immaterial nature, and such amendment shall become effective without any further consent of any other party to such
Loan Document other than the Administrative Agent and WPZ. 
 Section 9.04 Expenses; Indemnity; Damage Waiver. 

(a) (i) WPZ agrees to pay, within 30 days of receipt by WPZ of request therefor, all reasonable out-of-pocket costs and expenses of the
Administrative Agent in connection with the syndication, preparation, execution, delivery, administration, modification and amendment of this Agreement, the Notes, or any other Loan Document and the other documents to be delivered under this
Agreement, including the reasonable fees and out-of-pocket expenses of Shearman & Sterling LLP, counsel for the Administrative Agent, with respect thereto and with respect to advising the Administrative Agent as to its rights and
responsibilities under this Agreement, the Notes and any other Loan Document, and (ii) WPZ agrees to pay, on demand all costs and expenses, if any (including reasonable counsel fees and out-of-pocket expenses), of the Administrative Agent and
each Term Lender in connection with the enforcement (after the occurrence and during the continuance of an Event of Default and whether through negotiations (including formal workouts or restructurings), legal proceedings or otherwise) against the
Borrower or any Guarantor of any Loan Document. 

  
 62 








 (b) The Borrower agrees, to the fullest extent permitted by law, to indemnify and hold
harmless the Administrative Agent, each Term Lender (other than any Defaulting Lender) and each Related Party of any of the foregoing Persons (the “Indemnified Parties”) from and against any and all claims, damages, losses,
liabilities, costs, penalties, fees and expenses (including reasonable fees and disbursements of counsel) of any kind or nature whatsoever for which any of them may become liable or which may be incurred by or asserted against any of the Indemnified
Parties (other than claims and related damages, losses, liabilities, costs, penalties, fees and expenses made by one Term Lender (or its successors or assignees) against another Term Lender) arising out of, related to or in connection with
(i) any Loan Document or any other document or instrument delivered in connection herewith, (ii) any violation by the Borrower or any Subsidiary thereof of any Environmental Law or any other law, rule, regulation or order, (iii) any
Loan or the use or proposed use of the proceeds of any Loan, (iv) any transaction in which any proceeds of any Loan are applied or (v) any investigation, litigation or proceeding, whether or not any of the Indemnified Parties is a party
thereto, related to or in connection with any of the foregoing or any Loan Document (EXPRESSLY INCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, PENALTY, FEE OR EXPENSE ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH
INDEMNIFIED PARTY, BUT EXCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, PENALTY, FEE OR EXPENSE SOUGHT TO BE RECOVERED BY ANY INDEMNIFIED PARTY TO THE EXTENT SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, PENALTY, FEE OR EXPENSE RESULTED FROM
THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNIFIED PARTY). IT IS THE INTENT OF THE PARTIES HERETO THAT EACH INDEMNIFIED PARTY SHALL, TO THE EXTENT PROVIDED IN THIS SECTION 9.04(b), BE INDEMNIFIED FOR ITS OWN ORDINARY, SOLE OR
CONTRIBUTORY NEGLIGENCE. 
 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative
Agent under paragraph (a) or (b) of this Section, each Revolving Lender severally agrees to pay to the Administrative Agent, such Term Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense
or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability, cost, penalty, fee or related expense, as the case may be, was incurred by or asserted against the
Administrative Agent in its capacity as such. 
 (d) To the fullest extent permitted by applicable law, no party shall assert, and each
party hereby waives, any claim against any other party or any Indemnified Party, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement,
any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof; provided, however, that the foregoing limitation shall not be deemed to
impair or affect the indemnification obligations of the Borrower under the Loan Documents. No Indemnified Party referred to in paragraph (b) above shall be liable for any damages arising from the use by unintended recipients of any information
or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby. 

  
 63 








 (e) All amounts due under this Section shall be payable not later than 30 days after written
demand therefor, such demand to be in reasonable detail setting forth the basis for and method of calculation of such amounts. 

Section 9.05 Successors and Assigns. 

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Term
Lender and no Term Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in
accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or
transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Term Lenders) any legal or equitable right, remedy or claim
under or by reason of this Agreement. 
 (b) Assignments by Term Lenders. Any Term Lender may at any time assign to one or more
assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following
conditions: 
 (i) Minimum Amounts. 

(A) in the case of an assignment of the entire remaining amount of the assigning Term Lender’s Commitment and the Loans at
the time owing to it or in the case of an assignment to a Term Lender, an Affiliate of a Term Lender or an Approved Fund, no minimum amount need be assigned; and 

(B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this
purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Term Lender subject to each such assignment (determined as of the date the
Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000 and shall be an
integral multiple of $1,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, WPZ otherwise consents (each such consent not to be unreasonably withheld or delayed). 

  
 64 








 (ii) Proportionate Amounts. Each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Term Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned. 

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph
(b)(i)(B) of this Section and, in addition: 
 (A) the consent of WPZ (such consent not to be unreasonably withheld or
delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Term Lender, an Affiliate of a Term Lender or an Approved Fund; and 

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for
assignments if such assignment is to a Person that is not a Term Lender with a Commitment, an Affiliate of such Term Lender or an Approved Fund with respect to such Term Lender. 

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an
Assignment and Assumption, together with a processing and recordation fee of $3,500 (which fee may be waived by the Administrative Agent in its discretion), and the assignee, if it is not a Term Lender, shall deliver to the Administrative Agent an
Administrative Questionnaire. 
 (v) No Assignment to Borrower. No such assignment shall be made to the Borrower or
the Borrower’s Affiliates or Subsidiaries. 
 (vi) No Assignment to Natural Persons or a Defaulting Lender. No
such assignment shall be made to a natural person or a Defaulting Lender. 
 Subject to acceptance and recording thereof by the Administrative Agent
pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment
and Assumption, have the rights and obligations of a Term Lender under this Agreement, and the assigning Term Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under
this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Term Lender’s rights and obligations under this Agreement, such Term Lender shall cease to be a party hereto) but shall continue to be entitled to
the benefits of Sections 2.15, 2.17 and 9.04 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any purported assignment or transfer by a Term Lender of rights or obligations under
this Agreement that does not comply with this Section 9.05(b) shall be void, and any such purported assignment or transfer shall be treated for purposes of this Agreement as a sale by such Term Lender of a participation in such rights
and obligations in accordance with paragraph (d) of this Section. 

  
 65 








 (c) Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary
agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Term Lenders, the Credit Exposure, and principal amounts of the
Loans owing to (and stated interest thereon), each Term Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Term
Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Term Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection
by the Borrower and any Term Lender as to its own Commitments and amounts owing to it, at any reasonable time and from time to time upon reasonable prior notice. Upon its receipt of an executed Assignment and Acceptance, together with any Note
subject to such assignment, and the payment of any processing and registration fee, the Administrative Agent shall (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give
prompt notice thereof to the parties thereto. 
 (d) Participations. Any Term Lender may at any time, without the consent of, or
notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of
such Term Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Term Lender’s obligations under this Agreement shall remain
unchanged, (ii) such Term Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Term Lender receives the documentation required under Section 2.17(f) from such
participant (it being understood that the documentation required under Section 2.17(f) shall be delivered to the participating Term Lender), (iv) such Term Lender, acting solely for this purpose as a non-fiduciary agent of the
Borrower, maintains a register on which it enters the name and address of each participant and the principal amounts (and stated interest) of each participant’s interest in the Loans or other obligations under the Loan Documents (the
“Participant Register”), provided that no Term Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any information relating to a
participant’s interest in any commitments, advances or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan or other obligation is in
registered form for federal income Tax purposes or as otherwise required by law, and (v) the Borrower, the Administrative Agent and the Term Lenders shall continue to deal solely and directly with such Term Lender in connection with such Term
Lender’s rights and obligations under this Agreement. 
 Any agreement or instrument pursuant to which a Term Lender sells such a
participation shall provide that such Term Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may
provide that such Term Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in Section 9.03(b) that affects such Participant. Subject to paragraph (e) of this Section, the
Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, and 2.17 to the same extent as if it were a Term Lender and had acquired its interest by assignment pursuant to paragraph (b) of this
Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.09 as though it were a Term Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it
were a Term Lender. 

  
 66 








 (e) Limitations upon Participant Rights. A Participant shall not be entitled to receive
any greater payment under Sections 2.15 or 2.17 than the applicable Term Lender would have been entitled to receive with respect to the participation sold to such Participant unless the sale of the participation to such Participant is
made with the Borrower’s prior written consent. 
 (f) Certain Pledges. Any Term Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement to secure obligations of such Term Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank or any central bank having jurisdiction over
such Term Lender; provided that no such pledge or assignment shall release such Term Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Term Lender as a party hereto. 

Section 9.06 Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in
the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making
of any Loans, regardless of any investigation made by any such other party or on its behalf, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under
this Agreement is outstanding and unpaid. The provisions of Sections 2.15, 2.16, 2.17 and 9.04 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions
contemplated hereby, the repayment of the Loans or the termination of this Agreement or any provision hereof. 
 Section 9.07
Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall
constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all
previous agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement shall become effective on the Effective Date, and thereafter shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or pdf shall be effective as delivery of a manually executed counterpart of this Agreement. 

Section 9.08 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 
 Section 9.09 Right of Setoff. If an
Event of Default shall have occurred and be continuing, each Term Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time
or demand, provisional or final, in whatever currency) at any time held and other obligations (in 

  
 67 








 
whatever currency) at any time owing by such Term Lender to or for the credit or the account of the Borrower or any Guarantor against any and all of the obligations of the Borrower or any
Guarantor now or hereafter existing under this Agreement or any other Loan Document to such Term Lender, irrespective of whether or not such obligations of the Borrower or any Guarantor may be owed to a branch or office of such Term Lender different
from the branch or office holding such deposit or obligated on such indebtedness, provided that demand has been made to the Borrower for payment of such obligations. The rights of each Term Lender under this Section are in addition to other
rights and remedies (including other rights of setoff) that such Term Lender may have. Each Term Lender agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to
give such notice shall not affect the validity of such setoff and application. 
 Section 9.10 Governing Law; Jurisdiction; Consent
to Service of Process. 
 (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

 (b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the

judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent or any Term Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Borrower
or its respective properties in the courts of any jurisdiction. 
 (c) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in
paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01.
Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 

Section 9.11 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER

For purposes of this Section, “Information” means all information received from the Borrower or any of its Subsidiaries relating to the Borrower or
any of its Subsidiaries or any of their respective businesses, other than any such information that is available to the Administrative Agent or any Term Lender on a nonconfidential basis prior to disclosure by the Borrower or any of its
Subsidiaries. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own confidential information. 
 Section 9.14 Treatment of
Information. 

  
 69 








 (a) Certain of the Term Lenders may enter into this Agreement and take or not take action
hereunder or under the other Loan Documents on the basis of information that may contain material non-public information with respect to the Borrower or its securities (such material non-public information, “Restricting
Information”). Other Term Lenders may enter into this Agreement and take or not take action hereunder or under the other Loan Documents on the basis of information that does not contain Restricting Information. Each Term Lender acknowledges
that United States federal and state securities laws prohibit any person from purchasing or selling securities on the basis of material, non-public information concerning such issuer of such securities or, subject to certain limited exceptions, from
communicating such information to any other Person. Neither the Administrative Agent nor any of its Related Parties nor the Borrower nor any of its Related Parties, shall, by making any Communications (including Restricting Information) available to
a Term Lender, by participating in any conversations or other interactions with a Term Lender or otherwise, make or be deemed to make any statement with regard to or otherwise warrant that any such information or Communication does or does not
contain Restricting Information (except with respect to the Borrower and its Related Parties, pursuant to Section 9.14(b)), nor shall the Administrative Agent or any of its Related Parties nor the Borrower nor any of its Related Parties
be responsible or liable in any way for any decision a Term Lender may make to limit or to not limit its access to Restricting Information. In particular, none of the Administrative Agent nor any of its Related Parties nor the Borrower nor any of
its Related Parties (i) shall have, and the Administrative Agent, on behalf of itself and each of its Related Parties, hereby disclaims, any duty to ascertain or inquire as to whether or not a Term Lender has or has not limited its access to
Restricting Information, such Term Lender’s policies or procedures regarding the safeguarding of material, nonpublic information or such Term Lender’s compliance with applicable laws related thereto or (ii) shall have, or incur, any
liability to the Borrower or Term Lender or any of their respective Related Parties arising out of or relating to the Administrative Agent or any of its Related Parties providing or not providing Restricting Information to any Term Lender. 

(b) The Borrower agrees that (i) all Communications it provides to the Administrative Agent intended for delivery to the Term Lenders
whether by posting to the Approved Electronic Platform or otherwise shall be clearly and conspicuously marked “PUBLIC” if such Communications do not contain Restricting Information which, at a minimum, shall mean that the word
“PUBLIC” shall appear prominently on the first page thereof, (ii) by marking Communications “PUBLIC,” the Borrower shall be deemed to have authorized the Administrative Agent and the Term Lenders to treat such Communications
as either publicly available information or not material information (although, in this latter case, such Communications may contain sensitive business information and, therefore, remain subject to the confidentiality undertakings of
Section 9.14) with respect to the Borrower or its securities for purposes of United States federal and state securities laws, (iii) all Communications marked “PUBLIC” may be delivered to all Term Lenders and may be made
available through a portion of the Approved Electronic Platform designated “Public Side Information,” and (iv) the Administrative Agent shall be entitled to treat any Communications that are not marked “PUBLIC” as
Restricting Information and may post such Communications to a portion of the Approved Electronic Platform not designated “Public Side Information.” Neither the Administrative Agent nor any of its Affiliates shall be responsible for any
statement or other designation by the Borrower regarding whether a Communication contains or does not contain material non-public information with respect to the Borrower or its securities nor shall the Administrative Agent or any of its Affiliates
incur any liability to the Borrower, any Term Lender or any other Person for any action taken by the Administrative Agent or any of its Affiliates based upon 

  
 70 








 
such statement or designation, including any action as a result of which Restricting Information is provided to a Term Lender that may decide not to take access to Restricting Information.
Nothing in this Section 9.14 shall modify or limit a Term Lender’s obligations under Section 9.13 with regard to Communications and the maintenance of the confidentiality of or other treatment of Information. 

(c) Each Term Lender acknowledges that circumstances may arise that require it to refer to Communications that might contain Restricting
Information. Accordingly, each Term Lender agrees that it will nominate at least one designee to receive Communications (including Restricting Information) on its behalf and identify such designee (including such designee’s contact information)
on such Term Lender’s Administrative Questionnaire. Each Term Lender agrees to notify the Administrative Agent from time to time of such Lender’s designee’s e-mail address to which notice of the availability of Restricting Information
may be sent by electronic transmission. 
 (d) Each Term Lender acknowledges that Communications delivered hereunder and under the other
Loan Documents may contain Restricting Information and that such Communications are available to all Term Lenders generally. Each Term Lender that elects not to take access to Restricting Information does so voluntarily and, by such election,
acknowledges and agrees that the Administrative Agent and other Term Lenders may have access to Restricting Information that is not available to such electing Term Lender. None of the Administrative Agent nor any Term Lender with access to
Restricting Information shall have any duty to disclose such Restricting Information to such electing Term Lender or to use such Restricting Information on behalf of such electing Term Lender, and shall not be liable for the failure to so disclose
or use, such Restricting Information. 
 (e) The provisions of the foregoing clauses of this Section 9.14 are designed to assist
the Administrative Agent, the Term Lenders and the Borrower, in complying with their respective contractual obligations and applicable law in circumstances where certain Term Lenders express a desire not to receive Restricting Information
notwithstanding that certain Communications hereunder or under the other Loan Documents or other information provided to the Term Lenders hereunder or thereunder may contain Restricting Information. Neither the Administrative Agent nor any of its
Related Parties warrants or makes any other statement with respect to the adequacy of such provisions to achieve such purpose nor does the Administrative Agent or any of its Related Parties warrant or make any other statement to the effect that the
Borrower’s or Term Lender’s adherence to such provisions will be sufficient to ensure compliance by the Borrower or Term Lender with its contractual obligations or its duties under applicable law in respect of Restricting Information and
each of the Term Lenders and the Borrower assumes the risks associated therewith. 
 Section 9.15 Interest Rate Limitation.
Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the
“Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Term Lender holding such Loan in accordance with applicable law, the
rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of
such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Term Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate 

  
 71 








 
therefor) until such cumulated amount, together (to the extent lawful) with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Term
Lender. 
 Section 9.16 No Waiver; Remedies. No failure on the part of any Term Lender or the Administrative Agent to exercise,
and no delay in exercising, any right under this Agreement or any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any
other right. The remedies provided in this Agreement are cumulative and not exclusive of any remedies provided by law. 
 Section 9.17
Liability of General Partner. It is hereby understood and agreed that the General Partner shall have no personal liability, as general partner or otherwise, for the payment of any amount owing or to be owing hereunder or under the other Loan
Documents. Notwithstanding the foregoing, nothing in this Section 9.17 shall be construed to modify or supersede any obligation of the General Partner to restore any negative balance in its capital account (maintained by WPZ pursuant to
the Partnership Agreement) upon liquidation of its interest in the Borrower. 
 Section 9.18 USA Patriot Act Notice. Each Term
Lender and Administrative Agent (for itself and not on behalf of any Term Lender) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26,
2003)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Term Lender or the
Administrative Agent, as applicable, to identify the Borrower in accordance with the Act. The Borrower shall, following a request by the Administrative Agent or any Term Lender, provide all documentation and other information that the Administrative
Agent or such Term Lender reasonably requests in order to comply with its ongoing obligations under applicable “know your customer” and anti-money laundering rules and regulations, including the Act. 

Section 9.19 No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction contemplated hereby, the
Borrower acknowledges and agrees, and acknowledges its Affiliates’ understanding, that: (a) the credit facility provided for hereunder and any related arranging or other services in connection therewith (including in connection with any
amendment, waiver or other modification hereof or of any other Loan Document) are an arm’s-length commercial transaction between the Borrower, on the one hand, and the Administrative Agent and the Term Lenders, on the other hand, and the
Borrower is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents (including any amendment, waiver or other modification hereof or
thereof); (b) in connection with the process leading to such transaction, the Administrative Agent and the Term Lenders are and have been acting solely as principals and are not the financial advisors, agents or fiduciaries, for the Borrower or
any of its Affiliates, stockholders, creditors or employees or any other Person; (c) the Administrative Agent and the Term Lenders have not assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Borrower with
respect to any of the transactions contemplated hereby or the process leading thereto, including with respect to any amendment, waiver or other modification hereof or of any other Loan Document (irrespective of whether the Administrative Agent or
any Term Lender advised or is currently advising the Borrower or any of its Affiliates on other matters) and the Administrative Agent and the 

  
 72 








 
Term Lenders have no obligation to the Borrower or any of its Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other
Loan Documents; (d) the Administrative Agent, the Term Lenders and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and the
Administrative Agent and the Term Lenders have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (e) the Administrative Agent and the Term Lenders have not provided and will not
provide any legal, accounting, regulatory or Tax advice with respect to any of the transactions contemplated hereby (including any amendment, waiver or other modification hereof or of any other Loan Document) and the Borrower has consulted its own
legal, accounting, regulatory and Tax advisors to the extent it has deemed appropriate. The Borrower hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Administrative Agent or the Term Lenders
with respect to any breach or alleged breach of agency (other than against the Administrative Agent acting in its administrative capacity) or fiduciary duty; provided, however that it being understood and agreed that the use of the term
“agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any
applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties. 

Section 9.20 GP Buy-in. Notwithstanding any term or provision herein or in any other Loan Document, the parties hereto agree that
any GP Buy-in and any transaction related thereto is expressly permitted under this Agreement and each other Loan Document without any further action, waiver, consent or agreement by the Administrative Agent, the Joint Lead Arrangers, any other
agent or any Term Lender from time to time party hereto. As used herein, “GP Buy-in” refers to any sale, lease, transfer or disposition by Williams of its Equity Interests in the General Partner to WPZ.
